Wireless alarms, including an infrared system that detects motion, are a new alternative in home security devices. These easy-to-operate wireless alarms mount easily and can be used to protect a single room or an entire home. Depending upon your needs and price range, there are wireless alarm systems available for every lifestyle and budget. Whether you need a dual function door security bar to protect your garage, an infrared system that detects motion to protect your apartment, or a glass breakage alarm for your entire home, you can find a wireless alarm system to meet your needs.

Types of Wireless Alarms :

Room alarms are the most basic wireless home security devices, and use infrared technology to sense motion. Once activated, an infrared system that detects motion will sound an alarm when the unit senses movement within the room. Some of these infrared technology devices create an infrared triangle that covers the perimeter of the room, while others are designed to be used on specific entry points. These are the least expensive of wireless home security devices.

Other wireless home alarm systems operate more like a traditional hard-wired alarm, complete with a keypad and various sensors that are installed around the living area. These units are expandable and can protect a wide area without the necessity of hard wiring, including a magnetic door and window alarm. They also have the capability of adjusting the motion sensors to allow for pets inside the home, ensuring that the infrared system that detects motion does not accidentally believe Fido is an intruder.

Components of the Alarm System :

Most wireless alarms have a control panel with a keypad that serves as the "brains" of the unit. It interprets signals received from sensors that are placed around the house, and many have the ability of being programmed to dial a pager or telephone number if the alarm is activated.

Sensors can provide infrared technology motion detection coverage of individual rooms, and contact sensors can be attached to doors and windows, similar to a magnetic door and window alarm. All of these infrared technology devices are programmed into the main controller and will warn of movement into the protected area or through the protected access point.

Repeaters allow communication between sensor devices to expand the range of coverage. Many wireless alarms home security systems will allow up to 16 repeaters.

Moisture sensors are a handy addition to the basic wireless home security system that detect the presence of water and can warn of a flood. These systems can save the homeowner major headaches in cases of burst pipes or flooding from hot water heaters. Along the same idea, temperature sensors can telephone a homeowner to warn if the atmosphere inside the home has exceeded pre-programmed tolerances. This can help prevent damage from burst pipes due to freezing. Both of these features are add-ons to the basic home security system.
